checking compilation flags in Makevars ... NOTE
Package has both ‘src/Makevars.in’ and ‘src/Makevars’.
Installation with --no-configure' is unlikely to work. If you intended
‘src/Makevars’ to be used on Windows, rename it to ‘src/Makevars.win’
otherwise remove it. If ‘configure’ created ‘src/Makevars’, you need a
‘cleanup’ script.
